CNN has even reported that Steve Wozniak, the Apple co-founder, is currently at the front of the queue in his hometown of Los Gatos in California waiting to get the iPhone 4S. Apparently he's sat in a Pico armchair "sipping Diet Dr Pepper and scanning e-mails from his white iPad".

Powered by the dual-core A5 chip and Apple's latest iOS 5 operating system, the iPhone 4S features an eight megapixel camera, full HD video and voice control system Siri.

The iPhone 4S is available in either black or white. The 16GB handset costs $199 and 32GB $299. It is also the first iPhone to feature a 64GB model, priced at $399.
